Lanzatech makes the 2010 Guardian Cleantech 100

The 2010 Guardian Cleantech 100 was out yesterday. This list seeks to answer the question: which 100 of today's private cleantech companies are the most likely to make the most significant market impact over the next 5-10 years?

This year saw over 4000 nominations that were eventually funnelled down to around 200 companies, and then presented to an expert judging panel comprised of leading cleantech investors and corporations from Europe, the USA and Asia.

New Zealand company Lanzatech has made it onto this years list which is a fantastic achievement. Lanzatech uses a proprietary bacteria to convert 'dirty' waste gases from industry into ethanol that can be used as a fuel. It has run a pilot plant scale development to prove the technology at the Glenbrook Steel Mill, out of Auckland, since 2007, and has recently signed an agreement to build a demonstration plant at Baosteel's Shanghai steel mill.

Aside from Lanzatech's success in making the 2010 list, the site is a fantastic resource for what is happening in the cleantech sector right now. There is some incredible innovation happening - and proof that we have some of the solutions for combating climate change. The next challenge will be in how to scale them.
